IMPROVEMENTv IN HEATING-STOVES.

The Schedule referred ta in these Letters Patent andmakiug part of the sanne.

.To all whom 'it may concern:

Be it known that we, WILLIAM STARK and JOSEPH G. FISHER, of' Toledo, in the county ot' Lucas and in 'the State of Ohio, have invented certain new and useful Improvements in Heaters; anddo hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making a part of this specification and to the letters of referencemarked thereon, in which drawin'g- Figure 1 represents a front elevation of our device, and

Figure 2, a vertical cross-section' of the same looking from back to front.

Like letters of like kind denote similar parts in each figure.

The object of our invention is the construction of a novel heater for'use in dwelling-houses, railroad and street-cars, cabins of vessels, or other places Where heaters are used; and

The nature of the invention consists in 'the appli-v cation of water falling in drops upon the top of the fire-pot of the heater, for the purpose of making steam in the ,hot-air chamber of' the heater, and in the combination and arrangement of the devices employed.

In the drawing- .A represents the outer case or shell of the heater, made most conveniently of a cylindrical form, Oi' ,suitable sheet metal, provided with a cover, B,which mayV be made removable or not, vas is most convenient for the particular use to which the heatermay be applied, and with a close bottom, O. To this 'bottom legs Dv may be attached when desirable.

This shell is alsoprovided with doors E, for placing fiiol in the lire-pot, and F, for removing ashes; and this last door may have any suitable arrangement connected with it for regulating the draught.

Within the shell is placed there-pot G, so arranged as to leave an air-chamber, H, around it on all sides,

from the top to the bottom. of said shell.

This lire-pot has a top of conical: form,-wit h the point of the coneuppermost, and its base rests upon a plate, I, which covers the ash-box J.

The re-pot is 'provided with a suitable apparatus for shaking down the ashes and for emptying out the contents of the tire-pot.

Suitable perforatious, a, in the bottom of the shellv A, admit air tothe chamber H.

A smoke-pipe, K, leads out from the top of the fire-pot, and a hot-air pipe,- L, leads out from5the air-chamber, this last pipe being furnished with a damper, b.

A water-reservoir, M, is placed above the shell A, and connected with it by ahollow standard, N, which passes down through the /center of the cover B, and

terminates in a close conical end,"O, with the point of the cone downward, and in line directly over the center of the top of the :lire-pot.

This end O has one or more minute perforations, c, I near its point.

. The standard N has a valve, d, wherewith to regulate the flow of the water. w

In use this heater may be supplied with wood or coal, the lire kindled in the usual way, the reservoir M being tirst filled with water, and the valve a turned, so as to prevent the falling of the water upon the stove.

When the top of the tire-pot has become sufiiciently heated the valve d is turned so as to admit the passage of a very small 'supply of water into the endv O, through the perfolvjations of which it trickles, drop by drop, upon the top of the tire-pot; v

The fall of these drops Vshould be so regulated that each may be converted to steam as it strikes upon the top ot' the fire-pot.

The result of the conversion to steam offthese suecessive drops of water in the.hotair chamber is to force out the heated air more rapidly, and to impart a'certain degree of moisture to-such heated au'.

It is believed, moreover, as the resultof actual experiment, that the quantity of heat is. increased by this addition of steam over that obtained from the same amount of fuel burned iu this heater without I the use ot' steam, as described.

In the general use of this coutrivance it is intended that suitable piping be attached to the hot-air pipe L, so that heat may be conveyed to rooms other than that where the heater is placed, and in its use for railroad or street-cars that piping be att-ached which should pass entirely around said cars, or back and forth, lengthwise or crosswise.

To this last-named use it is believed that this heater is peculiarly adapted, owing to the force with which the hot air is expelled from the heater, which enables it to traverse long length of pipe rapidly.

Having thus ldescribed our invention,

- What we claim as new therein is 1. Theapplication of water in drops to the top of the nre-pot, within a hottair chamber, substantially as described and shown, for the purpose set forth.

2. The combination ofthe. reservoir M, standard N, hot-air chamber H, and irepotG, substantially as described, `for the purpose set forth.

K In testimony that we claim the foregoing we have hereunto set our hands this 28th day of October,

1870. WILLIAM STARK.A
